数字生态系统提供具有成本效益的数字服务，吸引并造福于其中的物种(即人类、组织和计算机)。数据广播作为数字信息传输的基石技术，为数字生态系统基础设施提供了强大的支柱。其可伸缩性特征对于包括移动广播服务在内的各种数字生态系统应用具有重要意义。提出了一种新颖的移动数据广播结构和接入方式。所提出的方案通过指定新的消息结构来解决最小化查询访问和调优时间的权衡。相应地，需要一种新的移动客户端访问和处理模式。我们研究了该方法在保持较低调优时间的同时最小化查询访问时间的有效性。我们的实验结果被用来与现有方法进行比较。实验结果证实了该方案的有效性。
Digital ecosystems offer cost-effective digital services that attract and benefit the species within them (i.e., humans, organizations, and computers). As a cornerstone technology for digital information delivery, data broadcast provides a strong backbone for the digital ecosystem infrastructure. Its scalability feature is highly significant for various digital ecosystem applications, including mobile broadcast services. This paper proposes a novel structure and access for mobile data broadcast. The proposed scheme addresses the tradeoff for minimizing query-access and tuning times by specifying a new message structure. Correspondingly, a new access and processing mode for mobile clients is required. We study the effectiveness of the proposed approach in minimizing query-access time while maintaining low tuning time. The results of our experiments are used to make comparisons with existing approaches. The results affirm the effectiveness of our proposed scheme.
